Unwanted users in Redhat LINUX

Hi All

After the installation of Redhat LINUX 4.0, many users exist by default in /etc/passwd.

Anybody can tell the users that can remove safely.

Thanks

Re: Unwanted users in Redhat LINUX

The users that are added by default to a RH Linux system are the users needed for the various subsystems that installed them.

'gopher' and 'games' are about the only disposable uid's I can think of.

Re: Unwanted users in Redhat LINUX

Leave 'em.

Ininstall packages you aren't using which created extraneous users.

Leave all the 'default' (core) users intact, as if you install a package down the track that might rely upon it, it could do bad things.

There's only 30 or so, so in the general scheme of things, it's not that great.

I run a mail system with some 60,000 active users (and about 340,000 inactive users). Having 30 'extras' is nothing.

(Oh, and for the nay-sayers, no I don't use passwd files for them. My passwd files have 45-50 lines in them).

Re: Unwanted users in Redhat LINUX

Hi Sajeesh,
The best advice here is:
simply don't remove users with UID below 100.
